But I have a question regarding the client I'm using. It does not appear to be "T2A", despite following the instructions for downloading.
Am I supposed to be seeing this?

It appears that I am running Age of Shadows, or Mondain's Legacy... Is this normal? I am running UO through the "Second Age" directory as downloaded on this site.
I also have up to date versions like Kingdom Reborn, Mondain's Legacy though.
